Machined from brass and finished with a zinc plating that meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this spacer provides a reliable standoff between a PCB and its mounting surface. It measures 0.75 inches in overall length, with an inside diameter of 0.116 inches and an outside diameter of 0.1875 inches. Electronics technicians, control board assemblers, and HVAC service pros use these spacers when mounting or replacing circuit boards in equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and commercial applications wherever a number 4 fastener is used to mount a circuit board. Common install scenarios include furnace control boards, air handler boards, and other low-voltage electronic assemblies that require a fixed standoff height of 0.75 inches between the PCB and the chassis. The female unthreaded body accepts a screw passed through the board, keeping the assembly square and secure without threading into the spacer itself.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts number 4 screws for straightforward PCB standoff mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating meets ASTM B633 and QQ-B-626 Comp 22 Type 1 specifications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.75 inches held to a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.116 inches with a tolerance of 0.000 to 0.010 inches for consistent fastener fit\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.1875 inches provides a compact footprint on dense PCB layouts\u003c\/li\u003e\n  \u003cli\u003eSold individually, compatible with single-unit purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service spacer for circuit board assemblies that use number 4 screw fasteners and require a 0.75-inch standoff height.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or HVAC service professionals during control board replacement or assembly work. Always de-energize the equipment and discharge any stored capacitor voltage before working on or near circuit boards. Use a fastener driver sized for number 4 hardware and avoid over-torquing, which can crack solder joints or the board itself. Follow applicable NEC guidelines when working inside electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.116 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S325M01F21E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51733061337394,"sku":"S325M01F21E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_649ba55b-e06a-4280-81bd-dc191cbe4862.jpg?v=1788751037","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s325m01f21e-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
